All of these are examples of projectile motion, where an object is launched into the air and moves along a curved path under the influence of gravity.
Throwing a baseball Kicking a soccer ball Shooting an arrow with a bow These are all examples of projectile motion where an object is launched into the air and moves along a curved path under the influence of gravity.
A projectile is an object moving through the air but people mainly think of a projectile as something you aim at someone and attempt to hit them with. A rock, a bullet, an arrow, a missle, all can be considered projectiles. The first sentence of the answer though is what you are looking for I think.
Doubling the initial speed of a projectile will quadruple its range, assuming all other factors remain constant. This is because the range of a projectile is directly proportional to the square of its initial speed.
The vertical velocity at the highest point of the trajectory, the vertical displacement when the projectile returns to its initial height, and the vertical acceleration at the highest point are all zero throughout the flight of a projectile.
The velocity of a projectile at its maximum height is zero. This is because at the highest point of the projectile's trajectory, all of its initial kinetic energy has been converted into potential energy, causing the velocity to momentarily become zero.

A projectile need not revolve at all in order to be a projectile.

Projectile motion is a form of motion wherein an object moves along a curved path under the action of gravity only. The height of a projectile in motion is dependent on gravity.
The vertical velocity at the highest point of the trajectory, the vertical displacement when the projectile returns to its initial height, and the vertical acceleration at the highest point are all zero throughout the flight of a projectile.
Doubling the initial speed of a projectile will quadruple its range, assuming all other factors remain constant. This is because the range of a projectile is directly proportional to the square of its initial speed.
Almost all of the aplicants that apply to a highly selective college do not get admitted.
The velocity of a projectile at its maximum height is zero. This is because at the highest point of the projectile's trajectory, all of its initial kinetic energy has been converted into potential energy, causing the velocity to momentarily become zero.
Examples of centripetal acceleration include a car turning a corner, a ball moving in a circular path on a string, and a planet orbiting around a star.
Either is correct, but the particular choice will depend on the usage. Only one is correct for a given application. Let's look at a couple of examples and see how each is used."We are seeking a housekeeping supervisor, and any person with a year experience is encouraged to apply.""We are seeking a housekeeping supervisor and all persons with a year of experience are encouraged to apply."The examples are compound sentences, as you can see. The relative portion of the examples is the latter one, and here they are broken out:"Any person with a year of experience isencouraged to apply.""All persons with a year of experience areencouraged to apply."In the examples, we see that "... person ... is..." and "... persons ... are ..." both meet the demands of proper English usage.
When a projectile is moving up, gravity is pulling it downward. Gravity is a force that acts on all objects, causing them to accelerate towards the center of the earth.
Any shape you like. A stone that is thrown is a projectile. A cannonball, arrow, spear, bullet are all projectiles. A projectile s an object all of whose momentum comes at the moment of launch; once it is launched, it travels under that initial momentum and external forces such as gravity and air resistance. There is no "on board" rocket or other means of propulsion.
